Perseids shower, august 2009

The Perseids are back, just like every year. Even though I’m a bit late with the announcement this year (the peak occurred last night, Aug 11th), I’m still a few hours early for tonight’s show, so I hope this helps… :)

In short, both tonight (Aug 12th) and tomorrow night (Aug 13th), you might want to grab a reclining chair or a blanket, go out in a place outside the city where you have as little surrounding light as possible, and look at the sky. If you have a clear sky, the show will most likely be spectacular.

With the Moon out (Last Quarter Moon occurs 23 hours after the Perseid shower peak), you’ll need a clear, dark sky to see more than just a few Perseids. “Dark” means at least 40 miles from the lights of a large city. You won’t need a telescope – in fact, the eyes alone work best because they provide the widest field of view.

In order to see the Perseids shower, you just have to face east, and look about halfway up. After midnight (around the time of moonrise), you may want to shift your view overhead. Glancing around won’t hurt anything. In addition to your chair/blanket, you can bring some bug spray, cookies/fruit, and a non-alcoholic beverage (alcohol interferes with the eye’s dark adaption as well as the visual perception of events). :P

How many Perseids will you see? This year, with a half-illuminated Moon in the sky, you can expect to count between 30 and 50 meteors per hour from a dark site during the peak period (Aug 11-13).

The Unexpected Hanging

A murderer had been found guilty of a particularly heinous crime. The judge sentencing the murderer decides that death is too good for him; he wants to make him suffer. He passes his sentence, by saying:

You will be taken from this place, and hanged from the neck until you are dead. Before that, though, you will suffer anguish, waiting, never knowing whether this will be the day that you will die. One morning, sometime in the next week, it will happen, but until it does you will live in fear.

The murderer leaves the courtroom with a light heart, knowing that the sentence handed down to him cannot be carried out.

He reasons like this:

Suppose that on the seventh morning I am alive. I will know that that is the day that I am to die. But the judge said that I would not know the day that I am to die. Therefore I will not be hanged on the seventh day. The sixth day is the last day that it could be.

But in that case, if I am alive on the sixth morning then I will know that it is the sixth day on which I am to be hanged. But the judge said that I would not know the day that I am to die. Therefore I will not be hanged on the sixth day.

He continues, applying the same reasoning to the fifth day, and then to the fourth, and so on, concluding that he cannot be hanged on any day according to the judge’s instructions. The sentence handed down to him cannot be carried out.

He is hanged on the morning of the third day, much to his surprise.

Russian army test

Apparently, this was pretty popular in Russian blogs lately, so I figured it would be fun to post it here as well.

Russian Army Test
So what you see is what to be said an entry level test leaked from Russian army. Here is the translation: “Six questions that help to identify any hidden psychological diseases young soldier might have. If the soldier can’t see the number in one of the 6 circles on the test picture, the he likely might be having:

Can’t see circle 1: High aggression, proneness to conflict, the recommendation is to add more physical exercise and cold showers.

Can’t see circle 2: Possible low than average intellectual abilities, can’t serve with sophisticated equipment.

Can’t see circle 3: Possible debauchery, soldier should get increased daily ration, should get more physical activity tasks, should not be connected to food supplies, etc.

Can’t see circle 4: Possible inclination to violence, can be assigned as a leader to his unit, as he can preserve discipline.

Can’t see circle 5: Possible latent homosexuality. Can be light uncontrolled accesses of attraction to the same sex.

Can’t see circle 6: Possible schizophrenic tendency. Required additional inspection.

Every soldier should be tested before assignment, according to the order #2299.

Osho, about vegetarians

Question: Are you a vegetarian?

Answer (Osho): Everybody here is a vegetarian. To be non-vegetarian is inhuman. The non-vegetarian is exactly equal to a cannibal, there is no difference, except that cannibals eat better meat than the non-vegetarians.

Comet Lulin getting closer

Comet LulinComet C/2007 N3, also known as Comet Lulin, is a non-periodic comet. It was discovered by Ye Quanzhi and Lin Chi-Sheng from Lulin Observatory on July 11th, 2007. On the morning of January 31, observers estimated the comet’s brightness as magnitude 6.5-7.0 (which means barely visible with the naked eye under close-to-perfect conditions). However, it’s getting closer… and brighter!

How much closer? Comet Lulin’s closest approach will be on February 24th, 2009 at a distance of about 61 million kilometers. Calculations indicate that by then, it will have an apparent magnitude somewhere between 4 and 6, and it’s tail will likely be as long as 8 times the Moon’s diameter.

The most interesting thing about closest approach, however, is the comet’s ridiculously high apparent velocity. Comet Lulin will be speeding along at more than 5° per day! This means that in a telescope or binoculars, one will actually be able to see the comet’s apparent motion against the background stars! This effect is a must-see, and does not present itself often.

The comet will also appear to pass near Saturn on February 23, and near Regulus in Leo on February 26 and 27. You can check out it’s trajectory on the dedicated NASA JPL small-body page.

I want to meet a Time Traveller!

Time Travel

Yes, I do! Seriously. :)

Okay, now let me explain. A few days ago, I did a quick web search that returned no results: I looked for the exact phrase “I want to meet a time traveller”, which returned no results – so I wondered, “Why are there no results?”. UPDATE: There is at least one result now, since Google indexed this article 2 minutes after I posted it. Also, the “single L” variant (as pointed by Lorand) does return one result… :)

Time travel itself is and has been a very fancy debate subject. Even more, there are people collecting money for a time when time travel will be possible, in order to pay other people to retrieve you from your current frame of reference (their past – your present) and bring you into the future (their present – your future). Still, it’s hard to believe nobody really tried the thing I’m about to do now…

Let’s take it one step at a time. Suppose at any one point in the future, they make time travel possible. And they make it available to everyone. And they make it cheap. At that exact point, time travellers will start “navigating” through the space-time continuum, creating all sorts of paradoxes, and perhaps even alternate universes in the process. But then again, that’s not really relevant. :)

What’s relevant is this: once all that happens, we should start meeting time travellers, since they’ll be all over the place. This however brings out the next question: if time travel is indeed possible, even if it will only be possible using future technologies, shouldn’t we have already met the guys/gals doing the travelling? Shouldn’t they already be here, if they do discover time travel in the future?

Well, the answer might be both yes, and no. Consider this: the year is 2508. You are a time traveller, and you’re considering going back 500 years in time, on Earth. But you have a very, very weird outfit (compared to the 2008 fashion trends), you don’t speak the language, you’re not aware of the customs. Plus, you just can’t cope with such rudimentary/old/ancient technology. In short, you’ll be a misfit, and for you it would be like going back to the Dark Ages, or perhaps the Stone Age.

So, what do you do? Well, I for one would try to blend in, not to raise any attention. Learn the language, fashion some clothes, try and adapt. And that’s perhaps one of the reasons time travellers haven’t been “identified” as of yet. Maybe they’re doing a really great job at adapting. :)

Now, what would a time traveller seek when time travelling? It may be landmarks, events, people… it may be anything. But also, time travellers may be people who tried searching the history archives for a book, a blog entry, a newspaper article, or a TV show where someone, somewhere mentioned that they wanted to meet a time traveller. And it only takes one time traveller that’s just crazy enough to humor the ones who wrote the articles, and come back in time in order to meet them.

Well, right now I’m one of those guys, doing the writing. So I’m saying this again, knowing that all this will be indexed in a search engine somewhere, or a forgotten history archive: it’s December 30th, 2008 – I’m Tudy, and I want to meet a Time Traveller! :D

Of course, you do realize (as do I) that if I do meet one such time traveller coming back for a while just to make my day, I will probably not be allowed to tell you anything about it, because of the consequences… ;)

Back from TechEd

I returned from TechEd ITPro last night, after a very long and interesting week. Quite a few amazing sessions with Steve Riley, Mark Minasi, Jesper Johansson, Mark Russinovich and many others. Lots of interaction in the “Ask the Experts” area, and plenty of new business opportunities as well.

All in all, the event was a pretty good one. Well, maybe except from the food. But that’s usually a general thing, since I’m a vegetarian. On two of my four flights this past week, the airline (TAROM) apparently “forgot” my previously confirmed request for a vegetarian meal. Even more so, when they brought the food (which was all with meat), I asked them what they can provide instead of that, and I was just told “we’re sorry sir, but we can’t really give you anything else – we’re not vegetarian ourselves!”. I mean, WHAT?!

They did have vegetarian meals at the conference, but I believe people fail to grasp the concept of being a vegetarian. They probably think salads contain enough nutrients, or that they can provide the needed vegetal proteins. But food-related things aside, the conference was a real success in my view.

I have no regret whatsoever as far as the sessions I chose to attend go (we’ll get all the others on a DVD anyway). Most of them were sessions which are a must-see, such as “Do these ten things now or else get 0wn3d!”, “Virtualization and Security: what does it mean for me?”, “How IT will change in the next 10 years and why should I care?”, “Privacy: the why, what and how”, “Q&A – Privacy, to be or not to be”, “It’s the 21st century: time to throw away your medieval gateways”, “The fine art of security panacea, achievable or not?”, “Naked dancing pigs and Werner Heisenberg: how security changes everything”, “The case of the unexplained”, “Anatomy of a hack” and several others, the ones here coming from the speakers I mentioned above.

I didn’t get much time to visit Barcelona, so I don’t have that many pictures. Even so, as soon as I sort them out, I’ll upload them online. I’ve sorted them a bit, so here they are.

The hotel was ok, the main quality being its central location. And again, thanks to Microsoft Romania for providing some very fun and interesting evening meetings all week long!

I’m now looking forward to my white hat hacking lab starting this weekend, since I see that the things are getting pretty hot already by just reading the comments… :D
